Semelab is a manufacturer of high performance semiconductor solutions, which can be found in the aerospace, space, defence and industrial markets.

Specialising in high reliability custom packaging components for critical applications, Semelab offer a wide product portfolio. This includes discrete semiconductors, power modules and RF transistors. Key applications for Semelab products include actuation, control systems, power generation and distribution.

Semelab MCAs offer a new way to build circuits from discrete components. They offer dramatic improvements in size, weight, reliability and cost compared to the same circuit built from separately packaged parts.

Key Features:

Multiple discrete components in a single hermetic package

Any technology: active, passive or mixed

Customers´ circuits implemented. Range of standard circuits

Small signal and power versions

Space Saving:

High component density

Light - typically 90% less weight

Easy interconnection

Up to 16 devices in one package

Weight saving: 10% of TO18 or 66% of LCC1

Space saving on the PCB

Higher reliability: 0.22 failures per 106 operating hours

Product Documentation

Specifically designed for high power audio amplifier output stages this new range of bipolar power transistors achieves unprecedented
levels of power in a compact package. They allow a significantly reduced footprint of the amplifier output stage with outstanding levels of
performance from both an audio and reliability perspective. They offer industry leading linearity and disoration performance with high gains
and low losses.

Together with Charcroft’s expertise, the Diode Leadless Chip Carrier is another great product from our Aerospace range that
works as a direct drop-in replacement for the standard MELF package.

Semelab are always striving to bring you the latest technologies which provide you with unique and innovative packaging solutions.

Semelab have taken the original MELF outline and added new thermal and assembly features. And because they build and screen parts here
in the UK, they are exempt from any ITAR restrictions.

Also offer Deep Dielectric Discharge protection and the Mil-19500 or ESA standard of screening flows.

Combining the unique attributes of Silicon Carbide and the advanced packaging techniques of Semelab, the SiC range offers unprecedented performance and reliability in the most extreme environments. Semelab Silicon Carbide parts are designed for use in motor drives, UPS, induction heating and SMPS, in applications such as down-hole drilling, aerospace engines and nacelles, defence and space applications. Optional screening levels and qualifications are available on the full range of parts.
